I'm using EssentialsX, I have signs enabled and they work as I want them too, unless I try and trade fireworks. How I think it should work: [Trade] 1 diamond 64 401:64 But it tells me 401 is an invalid ID. Using "64 Firework:64" doesn't work, unknown item. And Firework_rocket is to long to fit on a sign. Is there anyway to do this?
